The current sas_scsi_clear_queue_lu() is wrongly checking for commands
which match the pointer to the one passed in. It should be checking for
commands which are on the same logical unit as the one passed in. Fix
this by checking target pointer and LUN for equality.

The clear nexus I_T and clear nexus I_T_L functions in the aic94xx
specify the SUSPEND_TX flag which causes the sequencer to be suspended
until it receives a RESUME_TX. Unfortunately, nothing ever sends the
resume, so the sequencer on the link is stopped forever, leading to
eventual timeouts and I/O errors.
Since clear nexus commands are only executed as part of error recovery,
it's perfectly fine to keep the sequencer running on the link ... as
soon as the recovery function is completed, we'll send it the commands
to retry.

stex_internal_copy copies an in-kernel buffer to a sg list by using
scsi_kmap_atomic_sg. Some functions calls stex_internal_copy with
sg_count in struct st_ccb, which is the value that dma_map_sg
returned. However it might be shorter than the actual number of sg
entries (if the IOMMU merged the sg entries).
scsi_kmap_atomic_sg doesn't see sg->dma_length so stex_internal_copy
should be called with the actual number of sg entries
(i.e. scsi_sg_count), because if the sg entries were merged,
stex_direct_copy wrongly think that the data length in the sg list is
shorter than the actual length.

stex_direct_copy copies an in-kernel buffer to a sg list in order to
spoof some SCSI commands. stex_direct_copy calls dma_map_sg and then
stex_internal_copy with the value that dma_map_sg returned. It calls
scsi_kmap_atomic_sg to copy data.
scsi_kmap_atomic_sg doesn't see sg->dma_length so if dma_map_sg merges
sg entries, stex_internal_copy gets the smaller number of sg entries
than the acutual number, which means it wrongly think that the data
length in the sg list is shorter than the actual length.
stex_direct_copy shouldn't call dma_map_sg and it doesn't need since
this code path doesn't involve dma transfers. This patch removes
stex_direct_copy and simply calls stex_internal_copy with the actual
number of sg entries.

The libsas error handler has two fairly fatal bugs
1. scsi_sas_task_done calls scsi_eh_finish_cmd() too early. This
happens if the task completes after it has been aborted but before
the error handler starts up. Because scsi_eh_finish_cmd()
decrements host_failed and adds the task to the done list, the
error handler start check (host_failed == host_busy) never passes
and the eh never starts.
2. The multiple task completion paths sas_scsi_clear_queue_... all
simply delete the task from the error queue. This causes it to
disappear into the ether, since a command must be placed on the
done queue to be finished off by the error handler. This behaviour
causes the HBA to hang on pending commands.
Fix 1. by moving the SAS_TASK_STATE_ABORTED check to an exit clause at
the top of the routine and calling ->scsi_done() unconditionally (it
is a nop if the timer has fired). This keeps the task in the error
handling queue until the eh starts.
Fix 2. by making sure every task goes through task complete followed
by scsi_eh_finish_cmd().
Tested this by firing resets across a disk running a hammer test (now
it actually survives without hanging the system)

It's always been broken, but recent fixes actually made it do something,
and now the brokenness shows up as the resulting kernel simply not
working at all.
So it used to be that you could enable this config option, and it just
didn't do anything. Now we'd better stop people from enabling it by
mistake, since it _does_ do something, but does it so badly as to be
unusable.
Code to actually make it work is pending, but incomplete and won't be
merged into 2.6.25 in any case.

Sorry for the noise, but here's the v3 of this compilation fix :)
There are some places, which declare the char buf[...] on the stack
to push it later into dprintk(). Since the dprintk sometimes (if the
CONFIG_SYSCTL=n) becomes an empty do { } while (0) stub, these buffers
cause gcc to produce appropriate warnings.
Wrap these buffers with RPC_IFDEBUG macro, as Trond proposed, to
compile them out when not needed.
